I hope the lady in my congressman's office wasn't just feeding me a line. She called back about an hour after I ordered it and confirmed that it could be done. However, my optimism is tempered somewhat by the fact that he is a Democrat.
Maybe try your Senator's office. I'm pretty sure they can do it too.
Wayne, I have about as much chance of getting a flag out of Boxer or Feinstein's office as you have of winning the lottery! LOL
But I hope you receive your flag. :-]
